Novel hands-free pointer improves instruction efficiency in laparoscopic surgery.
OBJECTIVE: To determine if a novel, hands-free, multi monitor, pointer improves instruction efficiency in a simulated laparoscopy environment.METHODS: Twenty arbitrary instruction points were selected on a picture of a partially dissected cholecystectomy within a laparoscopic trainer box. A single instructor guided twenty trainees to locate points with a laparoscopic instrument. Points were visible to the… Continue Reading

Does an Infrared Laparoscope bring better visual field under the bleeding situation?
Back ground: The bleeding during the laparoscopic surgery adds much stress to the surgeons. Our experiences of near-infrared (NR) laparoscope that used for sentinel lymphnodes detection inspired the possibility of better visualization under the bleeding situation. Therefore, we examined the visibility of NR scope on an experimental basis.Materials and Methods: NR scope (805}15nm: Olympus Corp.)… Continue Reading
